Caterpillar has improved backhoe lifting capacity by as much as 25 per cent on the new Cat 440 and 450 centre pivot models.
The new addition to the Cat backhoe loader line-up, the 440 boasts a 25 per cent backhoe lifting improvement over the previous 430F2 and redesigned single tilt loader arms provide parallel lift and versatility in a multitude of applications.
The new 450 offers 15 per cent higher backhoe lifting capacity than the 450F and introduces a new cab for improved comfort.
Lift and tilt breakout forces have also significantly increased on both the 440 and 450 to improve machine productivity.
As well, a more balanced weight design and longer backhoe stabilizer legs improve operating stability.
The new stabilizer systems can be equipped with available guards to prevent damage to the cylinder rod, and optional leg plate guards prevent material build-up on the underside of the stabilizer leg.
The powertrains for both models are anchored by the Cat C4.4 ACERT engine that meets Tier 4 Final emissions standards using a service-free SCR solution for improved operating efficiency.
The standard Autoshift transmission features a sixth gear for improved roading performance, and an optional lock up torque converter for improved torque and efficiency on grades.
New spring-applied hydraulically released (SAHR) brakes provide simplified operation of the parking brake.
New backhoe hydraulic infrastructure
A completely reengineered hydraulic infrastructure for the operator station features seat-mounted controls to deliver a more comfortable operating position. Electronic sensors imbedded in the new design automatically detect the seat position.
The controls stay with the operator regardless of forward or reverse operation and eliminate the pilot control pods for backhoe operation, significantly increasing legroom at the rear of the cab. The control design allows the operator to sit at 45-degrees to the rear of the cab for increased operating comfort when truck loading and ditch clearing.
The backhoe loaders’ redesigned digital display centre with soft keys allows for fast and efficient setting of machine functions and offers clear visibility of the fuel and water temperature gauges and tachometer.

Up to 25 different user codes can be stored in the new models for operating security and quick pattern changes.
Single-tilt loader arms
Both backhoe loaders are built with common single-tilt loader arms. Electrical sensors positioned at the tilt and lift arm enable parallel arm movement for increased material retention when lifting the loader bucket and safe handling of palletized loads.
As well, in-cab, easy-to-set programmable kick out allows the operator to establish upper and lower arm positioning for repetitive work, like loading trucks. Additionally, return-to-dig limits can be set for efficient loader material excavation.
The 440 and 450 models can be retrofitted with the optional loader quick coupler that delivers quick work tool changes and increases versatility using the Cat Integrated Tool Carrier (IT) system.
Twist-to-connect quick disconnects for both the loader and backhoe arm attachments deliver fast connectivity.
The new backhoe loaders feature adjustable auxiliary hydraulic flow to the work tool to efficiently operate powered attachments.
